first of all, thx nfoav8or for you reply.

actually, i've got my built-in audio working at the moment. i installed a mpkg called alc888audio. it's easy to install, (some how like installing driver in windows) and worked just fine. but the weird thing is that there is no built-in audio recognized in system profiler...

the only main problem now left is the built-in ethernet. it's a nforce networking controller, VED_03EF VEN_10DE.

i've been trying forcedeth, but seems not working...
